Inertial Navigation System (INS) PCBA is an autonomous navigation component that operates without relying on external signals, making it critical for GPS-denied environments. It integrates high-precision gyroscopes, accelerometers, and advanced data processing chips, calculating the aircraft’s position, velocity, and attitude in real time with minimal cumulative errors. The PCBA is designed for compactness to fit the limited space of aircraft avionics bays, with high stability and anti-vibration capabilities. Our 10,000-square-meter production base and 2 function test lines ensure it meets the strict requirements of aviation navigation, supporting both civil and military aircraft for reliable operation in all flight scenarios.
